568-015 URETHANE 70 DURO ORINGS

APG stocks the U70015, an AS568-015 clear Polyurethane (AU/EU) 70 Shore A O-Ring with an inside diameter of 0.551 in (14 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.691 in (17.55 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against petroleum oils, abrasion and wear, and impact and shock loading. That behavior comes from the compound itself: Polyurethane (AU/EU) is widely chosen for outstanding extrusion resistance at elevated pressure and toughness that outperforms conventional rubber compounds. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Exposure to ketones or prolonged humidity at elevated temperature will shorten service life.

Typical settings include mining and heavy equipment, hydraulic cylinders, and high-pressure fluid power.

U70015 ships individually. Nominal inside diameter is listed as 9/16 inch. Check the compound against your process media, pressure and temperature before committing to a design.
